IMPROVEMENT IN ELEvAToR-BUCKETS.

Specification forming part of Letters Patent No. 188,565, dated March20, 1877; application filed December 30, 1874.

To all lwhom it may concern:

Be it known that I, FERNANDO C. BARBER, of Oxford, in the county ofOakland and State of Michigan, have invented au ImprovedElevater-Bucket, of which the following is a speccation:

The object of my invention is to so construct an elevator-bucket from asingle piece of sheet metal as that it will be stronger and more durablethan those heretofore used; and it consists in the peculiar outline orconfirmation of the blank, and in the manner of folding and joining itsprojections together, as more fully hereinafter set forth.

Figure l is a perspective View of the bucket. Fig. 2 is a plan ordiagram of the blank from which the bucket is formed.

In the drawing, A represents the blank of sheet metal from which thebucket is formed. The main or straight portion of the body of said blankforms the back and front ofthe cup. At one end of the main portion thereis a quadrantshaped projection, A', at each side, which projections formthe ends of the bucket, Which are not true curves, but present threeangular faces, as shown. On each side of the remainder ofthe body of theblank there are three projecting lips, c c c, which, when the front isfolded up against thev edges of the bucket ends,- are folded over saidends, and also overlap each other, as seen in Fig. l, and a rivet, d, isinserted through the end and laps of said iips to secure the Wholetogether. There is a lip, a, at the upper end of the back, which isfolded over upon itself. At the end of the front there is asimilarly-folded lip, b,

and in like manner a lip, a', is folded down at the top edge of eachend, all of which folds strengthen and stiifen the top edges of thebucket, every edge or corner exposed to friction being doubled, asdescribed.

What l claim as my invention, and desire to secure by'Letters Patent,is-

Au elevator-bucket, substantially of the shape shown, made from a singlepieceof sheet metal, and having the quadrant-shaped projections A, lipsc, lips a, a, and b, and rivets d, as and for the purpose set forth.
